Abstract

A method for the optimization of the configuration of multi-roll mill housings, particularly for mills of the cluster type constituted by two half-housings, said housings comprising eccentric rolls, first intermediate rolls, second intermediate rolls, and work rolls, characterized in that it comprises the steps that consist in:
  • calculating the coordinates of the center of rotation of first intermediate rolls, second intermediate rolls and work rolls on the basis of data related to the position of eccentric rolls and to the diameter of said eccentric rolls;
  • calculating a position value for said eccentric rolls which satisfies mechanical constraints set by the configuration of said mill;
  • calculating the current minimum distance between a line which is tangent to each work roll and a reference axis which represents the edge of the corresponding housing section; and
  • calculating the minimum and maximum values of the diameters of part of the rolls of the housing as a function of the diameter of the remaining rolls provided in the housing.
